This paper focuses on examining the effectiveness of three-dimensional (3D) computer models on student teachers’ academic achievement, mental model construction, and spatial ability used in learning the “atomic models” topic in this study. The students were randomly assigned into two groups: the treatment group (TG) where 3D computer models were used and the control group (CG) where models were not used for teaching. The treatment group was instructed using 3D computer models, while the traditional learning process was adopted in the control group. With the help of SPSS software, the independent-groups t-test and one way MANOVA were performed between the control and treatment groups. Cohen’s d and eta-squared values were calculated for the effects of the computer models. Through this study, it was seen that the instruction using 3D computer models contributed to students' achievement, mental model construction, and spatial ability more than the traditional instructional process.

This paper deals with the issue of model construction of the self-regeneration and self-replication processes using movable cellular automata (MCAs). The rules of cellular automaton (CA) interactions are found according to the concept of equilibrium neighborhood. The method is implemented by establishing these rules between different types of cellular automata (CAs). Several models for two- and three-dimensional cases are described, which depict both stable and unstable structures. As a result, computer models imitating such natural phenomena as self-replication and self-regeneration are obtained and graphically presented.

Objective To investigate the immediate effect of scalp acupuncture on walking pattern, using three-dimensional gait analysis (3D-GA), among patients in the subacute stage of intracerebral haemorrhage (ICH). Methods A subset of 30 patients with subacute ICH participating in a recently published randomised controlled trial who were able to walk independently were assessed by 3D-GA before and immediately after scalp acupuncture treatment (treatment group) or no intervention (control group) and the results presented here as a secondary analysis. The acupuncture manipulation was repeated three times with an interval of 5 min. Spatiotemporal and kinematic parameters during walking were collected and analysed using a 3D motion analysis system. Results After treatment, there were significant differences between the treatment and control groups in the spatiotemporal parameters of step length, velocity and cadence (p<0.05) and double-limb support. No significant difference was found in step width. When kinematic parameters were evaluated, the treatment group showed a significantly decreased peak pelvic anterior tilt angle and an increased hip extension angle after scalp acupuncture treatment, whereas the control group demonstrated no temporal changes. There were no significant changes in any other kinematic parameters in either group. Conclusions As the first exploratory study to investigate the effect of the scalp acupuncture on gait performance in patients with subacute ICH, this secondary analysis of a recent randomised trial suggested an immediate effect of treatment on spatiotemporal parameters. Improvement in gait pattern may be associated with a decreased anterior tilt of the pelvis and augmented hip joint motion during walking. Trial Registration Number ChiCTR-TRC-08000225; Post-results.

In recent years 3D modeling has been increasingly utilized during product design in lower secondary schools as well. Its greatest advantage over classical technical drawing and 2D drawing software lies in the fact students are able to observe the object they are designing from all the viewpoints of a virtual three-dimensional space. Since thinking and visualization in the process of object design also appear in three dimensions, the mental manipulation and guesswork required from students in order to add another dimension to an object pictured on a level plane are no longer necessary. Additionally, 3D modeling has a range of contributions to the cognitive development of children, which was also the subject of this research. The central question raised was whether students are able to improve their spatial ability by using modeling tools. The research included 196 students aged between 11– 15 years, of which 95 were placed in the experimental group and 101 in the control group. Spatial ability was measured using pre-test and post-test. Key words: 3D modeling, cognitive development, spatial ability, visualization.

This study set out to determine the effect of a training program on the amount of academic learning time in physical education (ALT-PE) provided by student teachers. A treatment group/control group experimental design was used to test the effect of an intervention, and random selection was used in assigning subjects to either group. A total of 50 classes were observed. Descriptive analysis revealed that teachers in the treatment group produced more ALT-PE than teachers in the control group. Wilcoxon Rank Sum tests computed for this comparison showed that the distribution of ranks was significantly different (p<.01). Additional tests produced nonsignificant differences for the distribution of ranks within the variables of skill practice, game, management, and waiting (p>.01). However, the general trend of differences within these variables seemed to contribute to the overall provision of greater ALT-PE for the treatment group. These findings have some important implications for the implementation of theory into practice in the supervision of novice teachers.

Cervical Spondylotic Radiculopathy

Cervical spondylotic radiculopathy (CSR) is the most commonly encountered cervical spine disorder. Cervical manipulation has been demonstrated as an effective therapy for patients. However, the mechanisms of manipulations have not been elucidated. A total of 120 cervical spondylotic radiculopathy patients were divided into the “three-dimensional balanced manipulation” treatment group (TBM group) and control group randomly. The control group was treated with traditional massage; the TBM treatment group was treated with “three-dimensional balanced manipulation” based on traditional massage. The symptoms and clinical efficacy of the patients were compared before and after treatment for one month. A three-dimensional finite element model was established. The mechanical parameters were imported to simulate TBM, and finite element analysis was performed. The results showed that the total effective rate was significantly higher in the TBM group compared with the control group. The biomechanical analysis showed the vertebral body stress was mainly distributed in the C3/4 spinous processes; the deformation mainly concentrated in the anterior processes of the C3 vertebral body. The intervertebral disc stress in the C3~C7 segment was mainly distributed in the anterior part of the C3/4 intervertebral disc, and the deformation extends to the posterior part of the C3/4 nucleus pulposus. In summary, these data are suggesting that TBM was effective in CSR treatment. The results of the finite element model and biomechanical analysis provide an important foundation for effectively avoiding iatrogenic injuries and improving the effect of TBM in the treatment of CSR patients.

Cardiac progenitor cell (CPC) therapy for heart disease has been examined enthusiastically. However, optimal scaffolds which maintain the transplanted cells are still elusive. We used clonally expanded stem cell antigen 1-positive CPCs from adult mice and produced a three-dimensional thick scaffold (CPC-scaffold), in which CPCs were cultivated up to 2 month with self-assembling peptide RADA16-I. Addition of designer self-assembling peptide containing the active motifs of 2-unit RGD binding sequence and IGF-1 promoted three-dimensional spreading and viability of CPCs. After making myocardial infarction (MI) with left coronary artery ligation in mice, we transplanted CPC-scaffold on the surface of infarction area and confined it inside of the pericardial space by closing parietal pericardium. Four weeks after transplantation, echocardiography showed that FS of treatment group (16±10%, n=17) was higher than that of control (MI only) group (10±6.8%, n=19) (P<0.05) and that LVDd of treatment group (5.4±1.0mm, n=17) was smaller than that of control group (6.2±1.1mm, n=19) (P<0.05). Infarction area was significantly decreased in treatment group (46±21%, n=17), compared to control group (59±19%, n=18) (P<0.05). Immunohistochemical staining for von-Willebrand factor (vWF) showed that the number of vWF-positive capillaries per mm2 in treatment group (16.8±3.2, n=5) was higher than that of control group(8.9±3.4, n=5) (P<0.05). There were many of CD31-positive capillaries with or without α-smooth muscle cell actin-expressing perivascular cells in the graft area. By using fluorescent-conjugated avidin, biotin-labeled scaffold was globally detected in the graft area 1 week after transplantation, but sparsely 4weeks after, suggesting that the transplanted scaffold was biodegradable. To examine whether transplanted CPCs remain in the scaffold, we labeled CPCs with red fluorescence protein (RFP). RFP+CPCs were observed in the graft area 4 weeks after transplantation of RFP+CPC-scaffold. FISH analysis showed that sex-mismatched CPCs were globally detected in the graft area on the surface of the heart. Therefore pericardial grafting of well-vascularized and cellularized CPC-scaffold was a useful method to improve cardiac function after MI.

The Impact

A test was done to see if reading a newspaper which consistently overrepresents foreigners as criminals strengthens the automatic association between foreign country and criminal in memory (i.e., implicit cultivation). Further, an investigation was done to find out if reading articles from the same newspaper produces a short-term effect on the same measure and if (1) emotionalization of the newspaper texts, (2) emotional reactions of the reader (indicated by arousal), and (3) attributed text credibility moderate the short-term treatment effect. Eighty-five participants were assigned to one of three experimental conditions. Participants in the control group received short factual crime texts, where the nationality of the offender was not mentioned. Participants in the factual treatment group received the same texts, but the foreign nationality was mentioned. Participants in the emotionalized treatment group received emotionalized articles (i.e., texts which are high in vividness and frequency) covering the same crimes, with the foreign nationality mentioned. Supporting empirical evidence for implicit cultivation and a short-term effect was found. However, only emotionalized articles produced a short-term effect on the strength of the automatic association, indicating that newspaper texts must have a minimum of stimulus intensity to overcome an effect threshold. There were no moderating effects of arousal or credibility pertaining to the impact on the implicit measure. However, credibility moderated the short-term effect on a first-order judgment (i.e., estimated frequency of foreigners of all criminals). This indicates that a newspaper’s effect on the strength of automatic associations is relatively independent from processes of propositional reasoning.
